Subsets intervals from a reference sequence to a new FASTA file.This tool takes a list of intervals, reads the corresponding subsquences from a reference FASTA file and writes them to a new FASTA file as separate records. Note that the reference FASTA file must be accompanied by an index file and the interval list must be provided in Picard list format. The names provided for the intervals will be used to name the corresponding records in the output file.
Usage example:
java -jar picard.jar ExtractSequences \
INTERVAL_LIST=regions_of_interest.interval_list \
R=reference.fasta \
O=extracted_IL_sequences.fasta

Overview
Simple command line program that allows sub-sequences represented by an interval list to be extracted from a reference sequence file.ExtractSequences (Picard) specific arguments
This table summarizes the command-line arguments that are specific to this tool. For more details on each argument, see the list further down below the table or click on an argument name to jump directly to that entry in the list.
Argument name(s) | Default value | Summary | |
---|---|---|---|
Required Arguments | |||
--INTERVAL_LIST |
null | Interval list describing intervals to be extracted from the reference sequence. | |
--OUTPUT -O |
null | Output FASTA file. | |
--REFERENCE_SEQUENCE -R |
null | Reference sequence file. | |
Optional Tool Arguments | |||
--arguments_file |
[] | read one or more arguments files and add them to the command line | |
--help -h |
false | display the help message | |
--LINE_LENGTH |
80 | Maximum line length for sequence data. | |
--version |
false | display the version number for this tool | |
Optional Common Arguments | |||
--COMPRESSION_LEVEL |
5 | Compression level for all compressed files created (e.g. BAM and VCF). | |
--CREATE_INDEX |
false | Whether to create a BAM index when writing a coordinate-sorted BAM file. | |
--CREATE_MD5_FILE |
false | Whether to create an MD5 digest for any BAM or FASTQ files created. | |
--GA4GH_CLIENT_SECRETS |
client_secrets.json | Google Genomics API client_secrets.json file path. | |
--MAX_RECORDS_IN_RAM |
500000 | When writing files that need to be sorted, this will specify the number of records stored in RAM before spilling to disk. Increasing this number reduces the number of file handles needed to sort the file, and increases the amount of RAM needed. | |
--QUIET |
false | Whether to suppress job-summary info on System.err. | |
--TMP_DIR |
[] | One or more directories with space available to be used by this program for temporary storage of working files | |
--USE_JDK_DEFLATER -use_jdk_deflater |
false | Use the JDK Deflater instead of the Intel Deflater for writing compressed output | |
--USE_JDK_INFLATER -use_jdk_inflater |
false | Use the JDK Inflater instead of the Intel Inflater for reading compressed input | |
--VALIDATION_STRINGENCY |
STRICT | Validation stringency for all SAM files read by this program. Setting stringency to SILENT can improve performance when processing a BAM file in which variable-length data (read, qualities, tags) do not otherwise need to be decoded. | |
--VERBOSITY |
INFO | Control verbosity of logging. | |
Advanced Arguments | |||
--showHidden |
false | display hidden arguments |

read one or more arguments files and add them to the command line
List[File] []
--COMPRESSION_LEVEL / NA
Compression level for all compressed files created (e.g. BAM and VCF).
int 5 [ [ -∞ ∞ ] ]
--CREATE_INDEX / NA
Whether to create a BAM index when writing a coordinate-sorted BAM file.
Boolean false
--CREATE_MD5_FILE / NA
Whether to create an MD5 digest for any BAM or FASTQ files created.
boolean false

Google Genomics API client_secrets.json file path.
String client_secrets.json
--help / -h
display the help message
boolean false
--INTERVAL_LIST / NA
Interval list describing intervals to be extracted from the reference sequence.
R File null
--LINE_LENGTH / NA
Maximum line length for sequence data.
int 80 [ [ -∞ ∞ ] ]
--MAX_RECORDS_IN_RAM / NA
When writing files that need to be sorted, this will specify the number of records stored in RAM before spilling to disk. Increasing this number reduces the number of file handles needed to sort the file, and increases the amount of RAM needed.
Integer 500000 [ [ -∞ ∞ ] ]
--OUTPUT / -O
Output FASTA file.
R File null
--QUIET / NA
Whether to suppress job-summary info on System.err.
Boolean false
--REFERENCE_SEQUENCE / -R

R File null
--showHidden / -showHidden
display hidden arguments
boolean false
--TMP_DIR / NA

List[File] []
--USE_JDK_DEFLATER / -use_jdk_deflater
Use the JDK Deflater instead of the Intel Deflater for writing compressed output
Boolean false
--USE_JDK_INFLATER / -use_jdk_inflater
Use the JDK Inflater instead of the Intel Inflater for reading compressed input
Boolean false
--VALIDATION_STRINGENCY / NA
Validation stringency for all SAM files read by this program. Setting stringency to SILENT can improve performance when processing a BAM file in which variable-length data (read, qualities, tags) do not otherwise need to be decoded.
The --VALIDATION_STRINGENCY argument is an enumerated type (ValidationStringency), which can have one of the following values:
- STRICT
- LENIENT
- SILENT
ValidationStringency STRICT
--VERBOSITY / NA
Control verbosity of logging.
The --VERBOSITY argument is an enumerated type (LogLevel), which can have one of the following values:
- ERROR
- WARNING
- INFO
- DEBUG
LogLevel INFO
--version / NA
